ABSTRACT
Drunk driving is a very dangerous behavior caused as a result of excessive consumption of alcohol
therefore causing distortion in the thought pattern of its victims with a large percentage being
drivers of vehicles of all forms. Most of the traffic accidents recorded in recent years are related
to drunk driving. Solutions have been proposed, devices developed, all to the sole aim which is
to reduce traffic accidents due to drunk driving, but none has been quite cable of impairing the
driver’s ability to drive. To this end, we model and design an alcohol triggered vehicle engine
lock system. This project’s ability to impair the driver’s ability to drive makes it stand out from
previous methods or devices developed to reduce road accidents due to drunk driving.
There are many things which can be done right when it comes to safety on the road. Today’s
technology enables us to create an advanced Traffic safety system which can avoid accidents,
save energy and lives of people at the same time. In this project, we will be working on
avoiding accidents due to drink and drive.
The idea is about making vehicles more self-regulating and automatic which may inform or combat
vehicle drivers under terrible conditions. The system consists of MQ-3 alcohol sensor to
continuously observe the alcohol blood concentration level, to discover the presence of liquor
in the breath of a vehicle’s driver. By placing sensor on steering wheel of the vehicle, the
system has the capacity to continuously check alcohol concentration level from the driver’s
breath.
This project is a prototype to what is proposed with the vehicle’s engine system represented with a
DC motor and its ignition system represented with a push button. The overall work was
implemented with a constructed work, tested working and perfectly functional.
